3 Claims.

This invention relates to the production of yarn packages, and relatesmore particularly to apparatus for the winding of yarn packages, such asbobbins and the like, with a magazine wrap or transfer tail.

As commonly understood in the textile art, a magazine wrap or transfertail is a portion of the inner end of the first yarn wound on the yarnsupport, which is so disposed as to be positively secured during thewinding of the remainder of the yarn package, yet freely available fortying directly to theouter end of the yarn on another yarn package. Thepurpose of providing a magazine wrap or transfer tail is to enable anuninterrupted flow of yarn to be maintained from a depletedyarn packageto a full yarn package adjacent thereto, as in a creel or other yarnpackage holder on which both packages are supported.

An object of this invention is the provision of simple, efficient, andinexpensive apparatus for winding yarn on to a bobbin in such a mannerthat a magazine wrap or transfer tail is provided.

Another object of this invention is to provide means for manually orautomatically applying yarn to a bobbin to form a magazine wrap ortransfer tail While the bobbin is revolving at high speed.

A further object of this invention i the provision of means for applyingyarn to a bobbin to form a magazine wrap or transfer tail wherein thelatter will be well separated from the main body of the yarn woundthereon.

A still further object of this invention is the provision of means forapplying yarn to a bobbin to form a magazine wrap or transfer tailwithout subjecting the yarn to any sudden increase in tension during theapplication of said magazine wrap or transfer tail.

Other objects of this invention will appear from the following detaileddescription and drawing.

In the accompanying drawing, wherein the preferred embodiments of myinvention are shown,

Fig. 1 is a side elevational view, partly in section, of one embodimentof my invention, showing an apparatus for applying yarn in the form of atransfer tail or magazine wrap to the top of a bobbin rotating at highspeed;

Fig. 2 is a front elevational View of another embodiment of myinvention, showing modified means for applying the desired transfer tailor magazine wrap to the bobbin; and

Fig. 3 is a plan view of the plate or spinning ring mounting which platelays on the ring rail during the normal traverse.

Like reference numerals indicate like parts throughout the several viewsof the drawing.

Referring now to the drawing and more particularly to Fig. 1, a yarn I0coming from any suitable source of supply such as a metier or spinningcabinet (not shown) passes downward and is threaded through a travelerll mounted on a spinning ring l2 carried in a ring holder l3, the latterbeing attached to a plate l4 that lies on the ring rai1 15. Plate I4 isprovided with two lips l6 and H, the former comprising a handle and thelatter being suitably drilled and provided with holes Hi. The bobbin i9,upon which the yarn is wound, is supported on a spindle 20 which isrotated at high speed by suitable driving means (not shown). The normaltraverse ofthe yarn if! being wound on rotating bobbin I9 is provided bya reciprocating vertical movement of ring rail it which is raised andlowered in timed relation by suitable means (not shown) to provide thedesired type of Wind on the bobbin. Plate I4 is fixed by lip I1 to asleeve 2| which rides on guide rods 22, only one of which is shown inFig. 1 of the drawing, provided with an adjustable top 23 at the headthereof. Rods 22 are supported in a bracket 24 fastened to the spindlerail 26 as by screws 25.

To provide the desired magazine wrap or transfer tail, the operatordoffs the full package, replaces it with one which is empty in the usualmanner and then throws on the yarn to start the wind. As soon as theyarn l0 begin to wind on to bobbin l9, the ring I2 and ring holder [3fastened to plate M, which parts are in normal operating positions, areraised by means of lip [6 on plate I4 to the limit set by stop 23, whichlimit is just above the normal traverse of the yarn ID as provided bythe reciprocating vertical movement of ring rail l5. This movement ofthe plate I4 places the latter in the position I4. With plate M in theposition I4, ring 12 is brought into position l2 and the yarn l0 windson and form a magazine wrap or transfer tail 2! at the head of bobbin Hijust below flange 28. As soon as the desired magazine wrap or transfertail 2'! is formed, the operator releases lip l6, preferably at the topof the stroke of ring rail l5. Plate I4 drops the short distance to ringrail l5 and in this position permits the yarn ill to wind on to bobbinIS in the normal manner building up into windings 29.

Since the magazine wrap or transfer tail 21 is well separated from themain body of the yarn, namely, windings 29, it is easily available as atransfer tail yet it is secure and protected at all times. Furthermore,since the vertical movement of plate I4 may be effected at any portionof the.

traverse stroke and is in a direction tending to slacken the yarn, nosudden tension is placed on the yarn during the application of thetransfer tail and injury to the yarn is avoided.

Referring now to Fig. 2, in which another embodiment of my invention isshown, the yarn III is threaded downward through traveler II and thrownon to bobbin IS in the usual manner. As

in Fig. 1, traveler II is mounted on a spinning ring I2, set in ringholder I3 which is attached to plate I4, the assembly laying on the ringrail I5 in normal operating position. Set in holes I8 of plate I4 are apair of g de rods 30, carryi stop 3I attached to the ends thereof. Rods39 pass through stationary bushings 32 carried in the lower spindleplate 33.

When it is desired to apply the transfer tail or magazine wrap 21 at thehead of the bobbin I9 just below flange 28, the operator grasps lip l6and raises plate I 4 carrying ring I2 and ring holder I3 as high as stop3! will permit. The position to which ring I2 is raised is just abovethe normal traverse of ring rail I5 causing yarn II] to wind on bobbinI9 just below flange 28 and to form the desired magazine wrap ortransfer tail 21. When the desired amount of yarn is Wound on in theform of the transfer tail 2?, plate I4 is released, preferably at thetop of the stroke of ring rail l5, so that a sudden tension is notapplied to the yarn II the ring I2 and ring holder I3 fall, and the yarnI0 is permitted to wind on to bobbin IS in the normal manner.

The magazine wrap or transfer tail applied in the manner described isheld firmly and securely on the yarn package and is amply protected bythe flange at the head of the bobbin. It may be easily detached andemployed for tying on to a reserve package, as is necessary when drawingthe yarn from the bobbin during warping operations.

It is to be understood that the foregoing detailed description is givenmerely by way of illustration and that many variations may be madetherein without departing from the spirit of my invention.

Having described my invention, what I desire to secure by Letters Patentis:

1. In a device for producing yarn packages having a transfer tail, thecombination with yarn traversing means, including a ring rail, a platenormally seated on said ring rail, a ring holder on said plate, aspinning ring in said holder and a traveler for winding yarn on arotating yarn holder, of manually operated means for raising said plate,the ring holder, ring and traveler from said ring rail to a positionbeyond the normal traverse of said ring holder, ring and traveler withrespect to said yarn holder, so as to cause the winding of a relativelysmall amount of yarn on the yarn holder at a point spaced from the mainbody of yarn, said small amount of yarn being available for use as atransfer tail.
